Submarines are some of the most annoying units (After Stealth
Bombers, of course).

Wouldn't it be nice to have a new unit to counter these? Such
as, Torpedo Aircraft, or even making the Gunboat capable of dealing
some (but little) damage to Submarines. Was going to suggest a
Helicopter to counter Submarines, but I guess that's already been
added.
